The OAC Computer, Radio and Battery unit is capable of operating over the full lunar night (375 hours without solar irradiation), without a need for hybernation mode. This is possible, with the help of OAC developed thermal design, combining structural rigidity and delicate thermal control of the system.
Thermal Analysis of the OAC unit

The technology for lunar missions have existed since the 1960s. OAC is using high-quality commercial-of-the-shelf (COTS) components to build affordable, high-performance space systems. The OAC Computer, Radio and Battery unit is capable of operating over the full lunar night, without a need for hybernation mode.

OAC contributed to the ESA ESTEC Deep Space Gateway and Lunar Exploration -industry days on 18th and 19th SEP 2017. It’s great to see that this time the Europeans are leading the path for permanent lunar base.
